THOMAS HANDLOSER, OF NEWYORK, Y.

METAL ROLL.

SPECIFICATION forming part of Letters Patent No. 375,352. dated December 27, 1887.

Application filed September 24, 1887. Serial No. 250,578. (Nomodeh) To all whom it may concern.-

Be it known that I, THOMAS HANDLOSER, a citizen of the United States, and a resident of the city of New York, in the county and State of New York, have invented new and useful Improvements in Rolls for Cold-Rolling of Metals, of which the following is a specification.

My invention relates to hardened-steel rolls for cold-rolling of metals, such as are used for flattening steel wire or for rolling hoop-steel. Great difficulties are experienced in hardening the steel rolls hitherto used, and a large percentage of rolls is ruined in hardening.

Rolls made in one piece can never be properly hardened to such a depth as not to require rehardening from time to time. The object of my invention is to obviate those difficulties, to reduce the loss in hardening, and to provide proper means for cooling by Water.

My invention consists in a compound steel roll consisting of a shaft upon which are mounted a series of hardened-steel disks; and it further consists in combining therewith a water-channel entering through the axis of one of the ends, passing to the periphery and through a spiral groove on the surface of the shaft, and finally passing out through the axis at the opposite end.

My improved compound steel roll is illustrated in the accompanying drawings, in which Figure 1 is an elevation; Fig. 2, a section through the disks with the shaft in elevation. Fig. 3 is a section of the shaft; Fig. 4, a view of one of the disks. 7

Similarletters refer tosimilar parts throughout the several views.

A is the shaft having a flange or shoulder, a, cast or forged on or otherwise rigidly at-. tached.

b is a threaded part of the shaft. The ends of the shaft are of the usual form for journals and for pinions or couplings. Holes 0 0', Figs. 221ml 3, are bored into the shaft at opposite ends in the axis. To the inner ends of said holes radial holes d d are bored; and the outer ends of the same connected by a spiral groove, 0, on the cylindrical surface of the middle part of the shaft.

B B B B are ring-shaped disks of hardened steel, which closely fit the shaft A at the middle part. They are forced upon the shaft against the flange a, and held in position by a nut, O, screwed upon the threaded part b of the shaft. By having a fixed flange or shoulder at one side and a nut at the other side the disks are firmly held and prevented from turning on the shaft Without the use of keys. The disks B are turned off and hardened before being mounted upon the shaft, and are after mounting ground off, so as to present the appearance of a solid roll. A current of water is passed through the holes a c d d and groove e for the purpose of cooling the disks, the water being admit-ted at one end by the usual well-known means and discharged at the other end or carried to another roll.

By forming the roll of a series of disks the weight of the parts to be'hardened is much smaller than that of a roll cast in one piece. The comparatively thin disks can be hardened all through, and if once put in place do not require rehardening. Loss in hardening is very much reduced by this arrangement, and injured parts of a roll can be readily replaced without causing the loss of the whole roll.

I am aware that cloth Wringers have been built up in rings; also, rolls for calico-printing; but I am not aware that prior to my invention it was known that sectional rolls could be used for cold-rolling of steel, or that compound rolls had ever been used for such purposes. I have demonstrated by costly experiments that the abovedescribed rolls are far superior to the rolls hitherto used for coldrolling of steel. 7

What I claim as my invention, and desire to secure by Letters Patent, is-

l. A compound roll for cold-rolling of metals, consisting of a shaft, a series of hardenedsteel disks mounted thereon, and a waterchannel formed on the surface of the shaft and connected with axial inlet and outlet, substan tially as specified.
